Title: Apparatus for a balanced three phase ac power supply in a computer having variable dc loads
Inventor: TIGHE DONALD J
IPC: H02M7/17
Filed: 1990-11-21
Abstract: A balanced three phase AC power supply (12) for a computer system having unbalanced, variable DC loads (34). AC to DC converters (18a-c) utilize high power factor correction circuitry to impose a sinusoidal current loading waveshape (23) substantially in phase with the AC voltage (24). Each AC to DC converter outputs equal DC voltages maintaining a balanced loading on the AC power source. The design and organization of the power supply components make the supply fault tolerant when one phase (~A, ~B, ~C) of AC power or one AC to DC converter is lost due to malfunction or servicing.

Title: Friction modifiers
Inventor: CHIDDICK KELVIN S
IPC: C10M169/04
Filed: 1992-05-20
Abstract: Friction  modifiers  are  compositions  which modify the coefficient of friction between surfaces to which the friction modifier  is  applied.   They  are similar  in nature to  lubricants  but have different characteristics in certain respects.   The  invention relates particularly to solid friction modifiers which may be rigid or flexible.   These friction modifiers comprise 20-80% by weight of a polymer medium, 5-20% by weight of a solid lubricant and 15-60% by weight of a friction  enhancer.     The  coposition  produces  a coefficient of friction which rises to above 0.20 at creepage levels up to 2.5% between steel bodies  in rolling-sliding   contact   lubricated   using   the composition.

Patent CA-2087460-A1 (CA)
Inventor: SALVUCCI FRANK S
IPC: B62B5/06
Filed: 1993-01-18
Abstract: A  removable  handle  for gas cylinder  hand  trucks  allows storage of the truck in a smaller space by decreasing the  height of  the truck. The invention is for trucks of the type  having  a tubular  handle  extending upward from the frame. The  joint  (or joints)  where the handle removes is formed by making a   cut  in the  tube,  preferably  just above the level of the  top  of  the frame. This cut becomes a joint  by adding to the cut a dowel and a bracket. The dowel is permanently fastened into the handle part of the tube, and snugly fits into the lower, or frame, end of the tube.  The  dowel both aligns and angularly braces the  two  tube sections.  The bracket part consists of two plates, one  fastened to the removable handle part and one fastened to the frame, which are  bolted together when the joint is fastened. The  plates  are radially attached to adjoining parts of the handle tube and frame tube.  Each  plate  has a hole for the bolt.  The  bolted  plates prevent relative twisting of the two tubes and also reinforce the dowel.  The  invention  is applicable to  either  a  single-joint upright tubular handle or a double-joint U-shaped tubular handle.

Filed: 1993-06-29
Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus (10) and method for applying thin film polymer labels to small cylindrical articles such as dry cell batteries without label mismatching is disclosed.          A label transport drum (42) is rotatably mounted on a frame (22).  Cut labels are supplied to the surface of the label transport drum as the drum (42) is rotated.  An adhesive is applied onto the area adjacent the leading edge of the label while the label is moving with the drum (40), and a solvent is applied onto an area adjacent the trailing edge of the label.   Cylindrical articles are conveyed in tangential spinning engagement with the label transport drum (42) and into rotative engagement with the adhesive on the leading edge of the label so as to transfer the label onto the article as the label is moved into engagement with the rotating article.  A pressure plate (134) imparts pressure against selected sides and ends of the article during wrapping to prevent mismatching of the label as the label wraps around the article.  A seam is formed at the overlap of leading and trailing edge portions.  The pressure plate (134) has an article engaging surface  (134a) positioned adjacent the surface of the drum (42).  The camber of the plate may be varied relative to the articles conveyed on the surface of the drum, thus varying the pressure imparted against selected areas of the article during labeling to prevent mismatching of the label.

Title: Propellant gas-generation system for canister ejection
Inventor: SOLBERG MARK A
IPC: F42B5/16
Filed: 1993-06-22
Abstract: A propellant system is disclosed which includes a propellant applied to at least one surface of a substrate which is in the form of a strip.  The propellant strip is adhesively attached to itself in a configuration which conceals propellant within the configuration and which allows the attached strip to peel away from itself under applied forces thereby resulting in smooth and continuous exposure of propellant for burning.  The system is directed to use with ejectable projectiles which are slidably disposed within a canister or casing. The propellant system is interconnected between the projectile and the cannister which houses the projectile.  The propellant is urged to peel, and thus expose propellant for burning, as the projectile is ejected from the canister. Alternatively, the propellant is telescoped and covered with a sleeve which peels away as the projectile is ejected.
Patent CA-2101840-A1 (CA)
Title: Transconductance Amplifier Circuit
Inventor: MILJANIC PETAR N
IPC: H03F1/34
Filed: 1993-07-08
Abstract: A transconductance amplifier circuit employs the known combination of a transconductance amplifier and a current comparator (with or without a range extender, preferably in the form of a two-stage current transformer) to compare the output current from the transconductance amplifier with that flowing through a reference resistor, both these currents having been derived from the same alternating input voltage. A current corresponding to the unbalanced ampere-turns in the current comparator is used to produce a feed-forward error signal that is used to modify the output of the transconductance amplifier.  The invention is characterized by an output transformer that has coaxial inner and outer toroidal magnetic cores, and primary and correction windings outside the outer core.  This primary winding receives the output current from the transconductance amplifier and the correction winding receives the error signal.  A winding located between the cores detects the error current in the output transformer (its magnetizing current), and injects this error current into the current comparator.  The secondary of the output transformer can be a single turn conductor extending through the hole formed by its toroidal cores.  The result of this circuit arrangement is that the output current in the secondary of the output transformer follows the amplitude and phase of the input voltage with a very high level of accuracy.

Title: Conveyor system for containers
Inventor: KLENK KLAUS
IPC: B08B9/42
Filed: 1993-11-04
Abstract: Abstract of the Disclosure Rows of bottles are conveyed on parallel running belts.  Closed loop flexible members such as roller chains,  run in vertical planes along the longitudinal  edges  of  the  belts  in  the  same direction as the belts.  The closed loop chains have stabilizing devices mounted to them for stabilizing the bottles in each row as they move along on the belts  beyond  a  bottle  infeed  region.     The stabilizing  devices  each  constitute  a  pair  of fingers that are pivotally mounted to pins that stand up from the closed loop chains and are spring biased so that they diverge at a predetermined angle from each other when they are not restrained from doing so.  As the sets of fingers are carried around on the chain, they reach a region where the bottles are deposited on the belts.   At least in this region,  the  fingers  of  the  stabilizing devices arrive between parallel  plates which cause  the fingers  to  pivot  towards  each  other  in  an overlapping relationship so that they are clear from the pathway defined by the belts.  After the bottles advance in a row, a small distance from where the fingers are restrained,  the fingers emerge from between the plates and the springs cause the fingers to diverge at an angle from each other and establish contact with bottles on the belt to stabilize them. The fingers swing in a horizontal plane so they use none of the head room above the bottles, thereby allowing for a more compact conveyor system.

Title: Method of treatment using steroid mouthwash
Inventor: EISEN DRORE
IPC: A61K31/57
Filed: 1992-04-10
Abstract: The object of the present invention is to provide a means of treating patients suffering from inflammatory conditions of the mouth using aqueous anti-inflammatory steroids in solutions that can be swished and expectorated as a mouthwash. Such therapy would allow direct contact of the medication with the diseased mucous membranes and would contact areas of the oral cavity that would not usually be reached with application of creams, gels, or ointments. Swishing for three to five minutes, then expectorating the aqueous anti-inflammatory-containing, results in maintenance of contact of the active agents with the oral cavity surfaces for a longer time than would application of gels containing those agents. The mode of application is simple and is not repugnant to the patient as is the application of creams, gels or ointments.
